I'll quickly explain the main focus:
Elpmaxe - An example for a basic star. It includes light curves, and the appropriate configuration for a star.
Tsemplis - The simplest one. It's just a basic gas giant, showing off the bare minimum in a Kopernicus config.
Dnourg - An example for ground (PQS.) This mainly focuses on the PQS node.
Riafolluf - It's full of air, not really... But it's an example for a properly functioning atmosphere.
Yretaw - It's watery... Meant to show the ocean node, and rings.

SunFix fixes Kerbol's light.
